Error while running the query in sql console

Hi,

I am getting the below error when I am trying to run a query. The query has 9 unions and 9 joins . I was getting the output earlier when I didnt put any calculated fields. But after I put some calculated fields I am not able to get the output and getting the below error. Now even if I remove the calculated fields I am getting the same error.

SAP DBTech JDBC: [2048]: column store error: search table error: [9] Memory allocation failed

Thanks in advance,

Ananth
